In today's digital world, cyber attacks are becoming more common. Even big companies like Marks & Spencer can be targets. What happened at the M&S cyber attack? This question has been on many minds since the incident first made headlines.
This wasn't just a small technical problem. The attack caused real issues. Shelves went empty in stores. Online shopping stopped working. Customer information was stolen. The company lost millions of pounds .
In this article, we'll explore everything about the M&S security breach. We'll look at how it happened. We'll see how it affected shoppers and the business. We'll also learn what companies can do to prevent such attacks in the future.
What Exactly Was the M&S Cyber Attack?
Understanding the Basics
The M&S cyber attack was a ransomware incident . Ransomware is like digital kidnapping. Criminals lock up a company's computer systems. Then they demand money to unlock them.

In this case, hackers used special harmful software called DragonForce . They took control of M&S's systems. They also stole customer information. Then they demanded payment from M&S to return access and delete the stolen data .
The People Behind the Attack
A hacking group called Scattered Spider was responsible for the attack . They are also known as Octo Tempest. This group is famous for using trickery rather than complex technical methods to break into systems .
These hackers used an affiliate service called DragonForce . This means other criminals can pay to use their hacking tools and methods. The same group also attacked other UK businesses like Co-op and tried to hack Harrods .
How Did the M&S Cyber Attack Happen?
The Simple Trick That Started It All
The hackers used a method called social engineering . This is a fancy term for tricking people. Instead of breaking through strong digital walls, they fooled a person into letting them in.
Here's how they did it: The hackers called the IT help desk. They pretended to be M&S employees who needed password resets . The help desk staff believed them and gave them access. This was like giving them a key to the entire building!
The Weak Spot: Third-Party Access
M&S's IT help desk was run by an outside company called Tata Consultancy Services . The hackers targeted this company first. They knew that sometimes security is weaker at partner companies.
Once they got into the help desk system, they could easily move into M&S's main systems. This shows why companies need to make sure their partners also have strong security.
Timeline of the M&S Ransomware Attack
The First Signs of Trouble
The problems started during the Easter weekend in April 2025 . Customers began noticing issues in stores. Contactless payments stopped working. Click & Collect order pickups failed.
At first, people didn't know these were signs of a major cyber attack. They thought it might be regular technical problems. But by Monday, April 21, it was clear something was seriously wrong.
The Long Road to Recovery
M&S couldn't fix everything quickly. The attack caused too much damage. The company had to carefully check each system before turning it back on. They needed to make sure the hackers were completely gone .
By June 10, M&S started taking limited online orders again . But this was only for fashion items in England, Wales, and Scotland. Click and collect service still wasn't available. Full recovery was expected by August .
The Impact of the M&S Data Breach

Financial Consequences
The cyber attack hit M&S hard in their wallet. The company estimated it would reduce profits by around £300 million . That's like losing £43 million every week .
The attack also affected M&S's value on the stock market. At one point, nearly £715 million was wiped off the company's share value . That's a huge amount of money!
Effects on Customers and Shoppers
Customers faced many problems because of the attack:
Empty shelves in stores because automated ordering systems weren't working
No online shopping for nearly seven weeks
Gift cards and loyalty points not working properly
Personal information stolen, including names, addresses, and order histories
One supplier even had to go back to using pen and paper for orders because the digital systems were down .
What Customer Data Was Stolen?
The hackers took personal information from M&S customers. This included:
Names and home addresses
Email addresses and phone numbers
Dates of birth
Online order histories
The good news was that no usable payment card details or passwords were taken . But the stolen information could still be used by criminals to create convincing scams .
Cybersecurity Lessons from the M&S Attack
How to Prevent Similar Attacks
The M&S breach taught important lessons about cybersecurity:
Use multi-factor authentication: This means requiring more than just a password to access systems. It could be a code sent to your phone or a fingerprint .
Train employees regularly: Staff need to learn how to spot trickery attempts. They should know never to reset passwords without double-checking who's asking .
Have better backup systems: Companies should keep copies of their data that can't be touched by hackers. This way they can restore systems without paying ransom .
Manage third-party risks: Companies must ensure their partners and suppliers also have strong security .
Create an "unplugging" plan: Sometimes, quickly disconnecting systems during an attack can prevent further damage, as Co-op did in a similar situation .
Why Human Factors Matter in Cybersecurity
Neil Hare-Brown, a cybersecurity expert, explained: "Most initial points of compromise are not highly advanced technical attacks but social engineering attacks on human beings" .
This means the weakest link in security is often people, not technology. Companies need to focus on both technical defenses and employee training.
Expert Opinions on the M&S Cyber Attack
What the Cybersecurity Professionals Say
Professor Alan Woodward, a cybersecurity expert from Surrey University, explained why recovery took so long: "Everything from knowing what has been sold, hence what needs replenishing, to taking card payments is very dependent on complex systems… it will take significant time and expertise to analyse and ensure they have expelled the hacker" .
Lisa Forte, partner at cyber security firm Red Goat, agreed: "They are handling the disruption in a mature way but to expect any company to get anything back online in a week is never going to happen. I don't know one organisation that could do it" .
The Bigger Picture for Retail Security
Julius Cerniauskas, CEO of web intelligence firm Oxylabs, highlighted the growing risks: "It's not a question of if you'll be targeted – but when" . He urged companies to improve both human and technical defenses.
The M&S attack showed that all retailers need to be prepared. Cybersecurity isn't just an IT issue. It's a core business function that affects everything .
Conclusion: Looking Forward After the M&S Security Breach
The M&S cyber attack taught important lessons to businesses everywhere. It showed that cybersecurity isn't just a technical issue – it's essential to keeping a business running .
The attack also reminded us that human factors are crucial in security. The best technology can be undone by one person being tricked by a convincing hacker .
As we move forward, companies need to think differently about cybersecurity. They need to test their defenses regularly. They must train their employees better. And they should assume that attacks will happen, so they need to be prepared .
For customers, the M&S data breach is a reminder to be careful with personal information. Use different passwords for different websites. Watch out for suspicious messages. And remember that even trusted companies can be targeted by cyber criminals.
The digital world offers many conveniences, but it also comes with risks. The M&S attack shows why we all need to understand these risks and take appropriate precautions.
